avahi-daemon 0.6.25-1ubuntu6.2 (amd64 binary) in ubuntu lucid

Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
It allows programs to publish and discover services and hosts
running on a local network with no specific configuration. For
example you can plug into a network and instantly find printers to
print to, files to look at and people to talk to.
.
This package contains the Avahi Daemon which represents your machine
on the network and allows other applications to publish and resolve
mDNS/DNS-SD records.
